Be it known that I, Eitxsr Gone BERN- HARD Kn'rixe, ii citizen of the Empire ol' Germany, residing useful lmprdvenients in Retort-Henting Apparatus; and I do hereby declare the following to be e full, clear, and exact description of the invention, such as will enable others skilled in the nrt to which it appertains to malte aud use the seine.

vThis invention relates to means for heating retorts of great length, and especiallyin coke and gas production.

Where the retorts to be heated exceed n length of about three meters, it has been found necessary to take some steps to insure the distribution of thc heat, otherwise the* extremities ot' the retorts lying more closely edfaccut to and remote from the furnace or heat-generating chamber would be uneduallv heated. It has been sought to solve this diliiculty b v providing in the.generating-chamber or the retort-chamber partitions to septiitite and direct the heating-gasesand also to use a pluralityoi" gcnerating-chambers feeding the diilercnt compartments of the retortchambei with combustible rlhe disadvantage has been that where separate heating-chnnil'iers are provided they must be'sepmately charged and regulated and where one is used the partitionscannot be made to equally distribute the heat, zuid es a 'result in either case theretorts are uiiequally lieittedy thereby'impairing the elliciencytr of the operation, adding to thc cost, and tlcpreciating the quality oi the product.

The object. of' this invention is the arrangement ol' colting-ijetorts and heat-generating chambers so ns to simplify thc charging and to reduc(` the necessity oi constant supervision, while insuring the equal heating ol' the dillerent portions of the retorts.

For purposes oi clucidation in the accompanying drawings :in embodiment of the invention is illustrated. l

in the drawings, Figure 1 is a vertical transverse scc-tion on the line t l ot' Fig. 3. Fig. 2 is a similar section on the line 2 `2 of Fig. l a vertical longitudimil sec- Fig. o. tion on the lim .3 Ii oi Fig. l. Fig. 4 is a simi- .lar section on thil lim` 1i 4 of Fig. i, and Fig. 5

is a simihir section on the line 5 2') ol" Fig. i.

Referring-to tl drawings in detailI the at tlariendorf, near Ber-4' hn, Germany) have invented certain new and r structure in which the retorts n lic is divided transversely by a wall 1 1, thus forming the retort-heating chamber into two compartments /clfind' c2, both of which are supplied with combustible gases from the twin generator, which is provided with the stepped grate t and the charging-door e. 'lhc generator is divided into two parts d tindj'bvv a p'iirtition gr, which projects do\.vnwtirdly from the iloor of the retort-heating chamber. The 'lower edge oi" the partition g occupies a position slightly lower than the normal level ofthe fuel in the generating-chtimber, the two coinpa'rtments d and f being therebyr isolated except for the communication through the porous bodyv ot fuel therein.

' The front generator-compiirtinent d Coniniunicntes by channels li with the frontrefor the passage from the compartment d to the com pertinent c of the combustible gases generated from the fuel. As the gases pass through the channels /i they come into contact and are thoroughly mixed with preheated air or other combustion-supporting gases from the channels i, as will be seen from Fig. 1. This air is warmed duringits cireuitous passage from the inlet n through the channels k and the openings m', connecting said channels. The incandescent-ges mixture plays about the retorts a in the retort-coinpartment c and having given up its heet to said retorts passes out through the openings o and 'through the circuitous channels p and lopenings g to the `smoke-flue s. It will be 'seen that the spent giises escaping from the rctort-compartmerit serve to preheat the incoming air, the channels It" and p lying alongside cach other in the sido wlalls of the Strueturc. i

The retti' generator-compartment'f coinmunicatcs with the rear retort-'coinpartinent ble gases from said gener-ittor-compurtmentj; passing through the channels It, tire intermixed with incoming nir through the chiinHels i2, the pi'clieating ot' the nir beingy effected by passing throughv the openingsnnt channels c2 fm2 an( serving to heiit that portion of the retort lying in the rear chamber c2, and the spent gases being carried oil through o, p2, g2, nud s2 inthe same way as described with relation to the gases generated in the forward generator-compartment d. It will thus be c2 by means of channels li, and the coinbustii ytort-coiiipetitment c, which channel serves loo i IOS -into compartments,

seen that the one twin generator serves to sup ply eombus ible gases to both the ret-ortcompartmen s c and C?, the gases' generated in the compartment d going 'to the compart ment c and those generated iii-the compartmentf going to the compartment t, whereb)Y both extremes ot the retorts (t lie in indeendent retort-eliambers and are vet heated )y combustible generated from a single charge of tuel, thus providing l'or the maintenance oi approximately the lsaine temperature throughout the retorts.

ln order to even more eliieientl)r govern the heat-ing of the retorts and bring the regulation thereof entirel iriiliin the control ol' the operator, dampersl u," and il? are provided in the outlet-lilies from botli retort-compartments at a point adjacent io the smoke-discharges s and These, dampers are independently adjustable to shut oil' to a greater or less degree the escape of the spent gases from either retort-coiapartment. .lt will be rediljiVT understood,that while both dampers are left open the combustible gases will pass in substantially equal quantities from the generating-conipartnient d and fthrough the compartment c and c2, maintaining substantiallT the same temperature in each, If, however, the damper u be closed in a greater or less degree, the effect will be to exert back pressure through the channels 71:', damming the combustible gases in the compartment c and prevent the entrance of more gas troni the generating-compartinent d. The result will be that the combustible gases will pass through the porous fuel in the generator- Chainber into the eonipi'irtnient and thence into the retort-compartanent e2, heating the rear portion of the retorts to a higher temperature. It, on` the other hand, the' damper ux' be opened and the damper u2 be closed, the eiiect will be reversed. It will thus be seen `that equable heating of the entire length of the retorts is provided for, coupled with means for efficiently regulating the heating of the same.

It will be obvious that the coinpartments into which the gencrating-chamber and the heatingchamber are divided may be'niultiplied toco'rrespond to an increased length oi' the retort to be heated Ordinar-iti' with a retort of three meters in length two compacti ments would su Hice.
